Setting Sail to Travel Through Space: 5 Things to Know about our New Mission

Our Advanced Composite Solar Sail System will launch aboard Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand no earlier than April 23, at 6 p.m. EDT. This mission will demonstrate the use of innovative materials and structures to deploy a next-generation solar sail from a CubeSat in low Earth orbit.

Here are five things to know about this upcoming mission:

1. Sailing on Sunshine

Solar sails use the pressure of sunlight for propulsion much like sailboats harness the wind, eliminating the need for rocket fuel after the spacecraft has launched. If all goes according to plan, this technology demonstration will help us test how the solar sail shape and design work in different orbits.

2. Small Package, Big Impact

The Advanced Composite Solar Sail System spacecraft is a CubeSat the size of a microwave, but when the package inside is fully unfurled, it will measure about 860 square feet (80 square meters) which is about the size of six parking spots. Once fully deployed, it will be the biggest, functional solar sail system – capable of controlled propulsion maneuvers – to be tested in space.

3. Second NASA Solar Sail in Space

If successful, the Advanced Composite Solar Sail System will be  the second NASA solar sail to deploy in space, and not only will it be much larger, but this system will also test navigation capabilities to change the spacecraft’s orbit. This will help us gather data for future missions with even larger sails.

4. BOOM: Stronger, Lighter Booms

Just like a sailboat mast supports its cloth sails, a solar sail has support beams called booms that provide structure. The Advanced Composite Solar Sail System mission’s primary objective is to deploy a new type of boom. These booms are made from flexible polymer and carbon fiber materials that are stiffer and 75% lighter than previous boom designs. They can also be flattened and rolled like a tape measure. Two booms spanning the diagonal of the square (23 feet or about 7 meters in length) could be rolled up and fit into the palm of your hand!

5. It’s a bird...it’s a plane...it’s our solar sail!

About one to two months after launch, the Advanced Composite Solar Sail System spacecraft will deploy its booms and unfurl its solar sail. Because of its large size and reflective material, the spacecraft may be visible from Earth with the naked eye if the lighting conditions and orientation are just right!

“Use your gifts and your talents to greatest possible effect while you can. Spread joy wherever possible. Laugh at jokes. Tell jokes. Make puns and bugger the embuggerances. Read books. Read my books. You might like them. You might find something else you like even more than them. Look for these things in life.

Question authority. Champion good causes. Speak out against injustice. Do not tolerate bullies or bigots or racists or anti-intellectuals or the narrow-minded. Use your education to challenge them. Broaden their perspectives. Make the world you interface with a happier place.

These are your choices. Choices you have been fortunate to have been given, so don’t waste them while you have them. Don’t look back in years to come and wish you had grasped a fleeting opportunity. Grasp it now with both hands, Live. Strive. Love.”

One of the greatest compliments I've ever received is that I resemble Sam Vimes.

Mind how you go.

"ALL-NATURAL"

Per la XVIII edizione di Share Festival vogliamo avanzare una proposta che sappiamo essere impossibile.

Qui nell'elegante Torino - città famosa per il suo caloroso sostegno verso ogni forma d'arte - non riusciamo a fare un respiro che non sia contaminato. Non è solo l'intera atmosfera del nostro pianeta a essere inquinata dai gas serra: a causa della sua eredità industriale e della sua peculiare situazione geografica, Torino si trova in una situazione particolarmente preoccupante per via dell'onnipresente foschia dovuta alle polveri sottili che includono metalli, prodotti della combustione e persino polveri agricole. Mentre voi leggete, noi stiamo respirando tutto questo.

Eppure, allo stesso tempo, la provincia piemontese è rinomata nel mondo per la sua dedizione all'artigianalità dello Slow Food, il cibo che nasce grazie alle varietà uniche di piante e animali presenti sul fertile suolo italiano.

Nel prossimo Festival vogliamo prendere di petto questa contraddizione e affrontarla attraverso il nostro mezzo d'elezione, l'arte tecnologica. Possiamo farla diventare un momento dialettico, invece che farla restare una mera contraddizione? Riusciremo a vedere della net-art plasmata sugli uccelli, gli insetti, le api e il paesaggio naturale e locale? Potremo interagire con robot fatti di legno, sculture digitali ricavate dal marmo e opere interattive composte da corni, canne, conchiglie, bambù, paglia, ossa, fossili o - ancor meglio - materiali naturali che rischiano di scomparire e interamente appartenenti alla regione da cui proviene l'artista?

"Difendere l'ambiente" non è sufficiente: questi materiali naturali saranno in grado di infiltrarsi nella sostanza innaturale del domani e prendersi la loro infestante, tremenda vendetta?

Fate del vostro meglio, per favore. Abbiamo bisogno di una boccata d'aria fresca!

For the XVIII edition of Share Festival, we make this demand because we know it's impossible.

Here in glamorous Torino -- a city known for its cordial support of "every form of art" -- we can't take one natural, untainted breath. Not only is the planet's whole atmosphere polluted with Greenhouse gases -- here in Torino, thanks to our industrial heritage and our specific geographic climate, we're particularly badly off from an all-pervasive haze of PM2.5 micrometer pollution particles, including metals, combustion products and even agricultural dust. As you read this, we breathe that.

And yet, at the very same time, our Italian province of Piedmont is world-famous for its devotion to hand-crafted, artisanal "Slow Foods" grown from the unique plant and animal varieties of the fruitful Italian soil.

In our forthcoming Festival, we plan to tackle this contradiction headlong -- through our favorite medium of technology art. Can this become a dialectic instead of a contradiction? Can we witness net.art that is all about birds, bugs, bees and natural local landscapes? Can we interact with robots made of natural woods, sculptures digitally carved from marble, and interactive artworks composed of horn, reeds, seashells, bamboo, straw, bones, fossils, or better yet, severely imperiled natural materials entirely unique to the artist's own region in the world?

It's not enough to "defend the environment" -- how can natural materials infiltrate tomorrow's unnatural substance and take some terrible, weedy revenge? Please do your best for us. We need a breath of fresh air!

My first actual portrait in a year and it‘s… a ghoul. 😂

But hey, it‘s THE Ghoul, and it‘s Walton frickin' Goggins. How could I not?? 😌

I loved the Fallout show so much, I watched it twice in a row lol.

I hate "influencers".

I'm part of a survey panel right now and they keep asking how much "influencers" influence me. They don't. They're paid shills. I hate them and I hate that they are thing. GAH.
